What is the area of the shaded portion of the circle?

Mathematics

Answer:

1st option

Step-by-step explanation:

the area of the shaded portion is calculated as

area of sector - area of white Δ

area of sector = area of circle × fraction of circle

                        = πr² × \frac{90}{360} ( r is the radius )

                        = π × 8² × \frac{1}{4}

                       = 64π × \frac{1}{4}

                       = 16π in²

area of Δ = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here b = h = 8

area of Δ = \frac{1}{2} × 8 × 8 = \frac{1}{2} × 64 = 32 in²

then

area of shaded portion = (16π - 32 ) in²
